Answer:
the width is 5 and the length is 23
Step-by-step explanation:
2x+2(4x+3)=56
10x+6=56
10x=50
x=5
4(5)+3=23
Answer:
B
Step-by-step explanation:
6n - 2(4n + 7) + 4= -2 firstly you open the bracket
6n - 8n - 14 + 2 = -2 then you collect the like terms
6n - 8n= -2 + 14 - 4 then add and subtract and divide by the coefficient
-2n= 12 - 4
-2n = 8
= n = 8 ÷ -2
n = -4
To find the total increase, we will subtract -14 from 36.
36--14=50
(A double negative is a positive.)
50 is your final answer.
Solve for the first variable in one the equations then substitute the result into the other equation so the answer is (2,5)
You have to distribute the minus sign to the second parenthesis, changing the sign of every term:
